A system for controlling the atmosphere in the container comprises a membran e separation apparatus and a second separation apparatus, adapted to separate nitrogen and to separate carbon dioxide and water vapour respectively from a gas mixture in the container comprising nitrogen, oxygen, carbon dioxide, water vapour and ethylene. The separated nitrogen is returned to the container, as is at least a portion of the carbon dioxide and water vapour, so as to produce and/or maintain a pre-determined atmosphere composition within the container thereby to preven t spoilage of perishable products within the container.
